TECHNICAL FIELD

The invention relates to a generator which is generally used in the textile field and integrated into the steaming machines enabling the dying material of the pattern-printed or plain-dyed fabrics dyed with the various dyes to be bound on the fabric such as not to be removed again.

In particular, the invention relates to a generator enabling the dyed fabrics to be kept in the saturated steam, superheated steam or hot air conditions for a certain period of time, which is capable of forming each of these three phases.

PRIOR ART

Today, various machines are used in many areas, primarily in the textile sector, for the purpose of exposing the products to steaming air or hot air and drying process. These machines generally consist of the main body where the process is carried out and the external steam or hot oil boilers where the heat is provided. Disadvantages of existing systems are described below.

-   -   a) Steam boiler rooms are difficult to install and operate.     -   b) It is a source of serious danger due to being a pressurized         container.     -   c) Even if steam is partially required in the plant, all boiler         rooms are operated and all conveyor lines are kept hot, which         causes serious energy losses.     -   d) Due to long conveyor lines, energy losses, pressure drops,         water-hammer impacts, faucet faults (condensate, pressure         reducer, control valve faults etc.) are inevitable.     -   e) The temperature is limited depending on the maximum working         pressure of the installed boiler. (Pressure/Saturated Steam         Temperature)

The utility model No. CN202644178 titled “Digital Continuous Steam Ager” which received protection in China is a machine of the type mentioned above and it is used for heat treatment of fabrics. Said invention receives the steam it needs from an external source via a pipe assembly. Thus, the installation costs are very high and occupies too much space. Moreover, due to the need for establishing a connection between the machine and the steaming source, loss of time occurs and labor costs increase. Besides, energy losses also occur.

Another patent is the European patent no. EP2195575B1, titled “overheated steam generator”. The said invention includes a rectilinear pipe segment (1); an electric resistor (3) wound about said rectilinear pipe segment and supplied by an electric source; a wound pipe segment (2), one end of which is connected to said rectilinear pipe segment, which is wound to form a cylindrical spiral which covers said electric resistor. However, when the details of the invention are examined, it is seen that it is a completely different method.

Furthermore, the Patent Application No. TR2014/05976 owned by the present applicant relates to a steaming, heating and drying machine which comprises all the elements used in areas in which products require steam air, hot air and drying processes and which comprises a main body housing and preserving all the elements and a process chamber located inside said main body and in which the products are treated, characterized in further comprising a heat source providing heat and a heat transfer cell in which said heat source is located and which can be filled with water in order to generate steam when needed.

In the said invention, the water in the heat transfer cell filled with water was heated to produce steam and the resulting steam was used in the process. The most important difference compared to the present invention is: In the present invention, a structure not filled with water is used. The most important difference of the method according to the invention is not to heat the water, but to wash the dried air and make it saturated by spraying the water onto the hot surfaces.

When the above applications are examined, it is clear that they are not a similar invention that eliminates the technical problems mentioned.

OBJECTIVE OF THE INVENTION

The main object of the invention is to develop a generator in the textile field, which is integrated into the steaming machines enabling the dying material of the pattern-printed or plain-dyed fabrics dyed with the various dyes to be bound on the fabric such as not to be removed again.

Another main object of the invention is to develop a generator enabling the dyed fabrics to be kept in the saturated steam, superheated steam or hot air conditions for a certain period of time, which is capable of forming each of these three phases.

A further main object of the invention is to enable the dried air to be washed and made saturated by spraying the water onto the hot surfaces not filled with water.

A further object of the invention is to condition the air with the heating battery and wash and saturate the dried air by spraying water on various hot surfaces.

A further object of the invention is to direct the washed and conditioned air back into the system through the fans.

DETAILED DESCRIPTION OF THE INVENTION

The invention relates to a generator which is generally used in the textile field and integrated into the steaming machines (chambers) enabling the dying material of the pattern-printed or plain-dyed fabrics dyed with the various dyes to be bound on the fabric such as not to be removed again, which enables the dyed fabrics to be kept in the saturated steam, superheated steam or hot air conditions for a certain period of time, and which is capable of forming each of these three phases.

FIG. 1 shows a general schematic drawing of the generator according to the invention. As shown in the FIGURE, the fabric (B) moves in the suspension bars so as to remain for a desired time in the chamber (A). The entry point (1) of the ambient air to the system and the entry point (2) of the conditioned air from the system to the ambient are shown on FIG. 1.

When the saturated vapor air is requested from the system; the waste return air, which is taken through the entry point of the ambient air into the system by the circulation fan (F) and polluted by the low-temperature gases resulting from the fix reaction, is washed by the water pressurized through the water conditioning system (D) and sprayed by the nozzles and sent to the heating battery (C).

The return air washed with the water sprayed through the nozzles (E) and simultaneously re-humidified meanwhile is heated around 3-6° C. over the saturated vapour temperature (100° C.) in the gas or fluid fuel heating cell by the heating battery (C) or by the superheated oil battery to be heated before and located in the region of the heating battery (C) and passed through the separator (G) and brought into the homogenized condition after its pressure being increased and sent to the chamber (A) through the entry point of the ambient air into the system (1).

When the superheated steam air is wanted, the outlet temperature is set to the desired temperature (110-250° C.) while the process and the system are the same as those described above.

When the hot air is needed or partial fresh air inlet is required; the fresh air inlet (H) is opened by setting the heating battery (C) to the desired hot air temperature without operating the water conditioning system (D) (pressurization, level, flow, water supply and drainage system) while the process and the system are the same as described above. Thus, the dry hot air is sent to the chamber (A), the suspended fabric (B) is dried, the returning air is reheated, partially renewed, and the waste ambient air is removed by the chimney fan (K).

A generator has been developed, which allows the dyed fabrics to be kept in saturated steam, superheated steam or dry hot air for certain periods of time, which is capable of forming each of these three phases.

By means of the system according to the invention, it is ensured that the dry hot air is both washed and saturated by spraying water to the hot surfaces which are not filled with water, the air is conditioned with the heating battery, the dried air is washed and saturated by spraying with water to various hot surfaces, the washed and conditioned air is redirected to the system through the fans.

All these processes are carried out by means of the system integrated into the chamber according to the invention, the energy, production costs are significantly reduced, the need for the systems such as external steam boiler, hot oil boiler etc. has been eliminated. In addition, the systems such as the steam boiler and the fluid carrying installations between chamber are eliminated.
